Not all networks have DHCP servers. Also, the DHCP process can sometimes fail to work properly. There are various methods for hosts to perform autoconfiguration when DHCP is not available. You should also understand how IPv6 networks use autoconfiguration and appreciate differences in the way DHCPv6 functions, compared to DHCPv4.

Every host interface needs an IP configuration to communicate on a TCP/IP network. An administrator can manually assign these IP addresses, or the assignment can be done automatically. By understanding the different methods available to you for assigning IP addresses, you can choose the method that best suits different networks and hosts.
You have seen how IP provides addressing and delivery at layer 3 of the OSI model. At layer 4, the TCP/IP protocol suite also defines how different applications on separate hosts establish connections and track communications. Understanding how application protocols use ports to establish connections is critical to being able to configure and support network services.

Ethernet, switching, and IP routing are the principal technologies used to implement cabled local networks. There are many types and sizes of network, however, and many different ways of designing cabling and forwarding to suit the requirements of large and small organizations and budgets. While you might not be responsible for network design at this stage of your career, it is important that you be able to identify the components and advantages of the tiered network hierarchies used to implement complex local networks.

When a private network is connected to public ones, traffic between the private and public zones needs to be subject to rules. This filtering role is performed by a firewall. Firewalls apply access controls to ensure authorized use of the network. They perform a filtering function to analyze the properties of connection requests and then allow, deny, and/or log them as appropriate. While you may not be installing and configuring these devices at this stage in your career, it is important that you understand their use on the network edge.

As well as understanding the different types of routing algorithms, you must be able to install routing devices to an appropriate place in the network. This lesson will help you to understand the role of routers placed at the network edge or perimeter. On IPv4 networks, this role involves the use of Network Address Translation (NAT) to manage communications between public and private address schemes.
Why is there a requirement for network address translation?
What is the difference between static NAT and dynamic NAT?
What is port forwarding?
What is the difference between NAT and PAT?
